Message from the Program Director

Welcome to the �� Clinical Neurophysiology Fellowship webpage. �� offers training in a 12-month, ACGME-approved Clinical Neurophysiology Fellowship program. The program is based in the Baylor Comprehensive Epilepsy Center (NAEC Level IV) and the Peter Kellaway Section of Neurophysiology, Department of Neurology, ��.

The program includes training in outpatient and inpatient EEG (adult and pediatric) including continuous video EEG monitoring, ambulatory EEG, quantitative EEG, evoked potentials, polysomnography, intraoperative monitoring, electrocorticography, EMG and nerve conduction studies. Sites of training include: Baylor Comprehensive Epilepsy Center, Baylor St. Luke’s Medical Center, Michael E. DeBakey Veterans’ Affairs Medical Center, and Texas Children’s Hospital.

Both adult and pediatric training tracks are available. Fellows can choose from a track with emphasis on EEG or a dual EEG/EMG track.

Senior faculty of the program include: Thomas E Lloyd, M.D., Ph.D., chair, Department of Neurology, Alica Goldman, M.D., director, Baylor Comprehensive Epilepsy Center and head, Peter Kellaway Section of Neurophysiology and Anne E. Anderson, M.D., Texas Children’s Hospital. The EMG portion of the program is directed by Nicolaas Anderson, D.O., M.S. At the completion of the fellowship, fellows will be eligible for the ABPN with added qualifications in clinical neurophysiology, ABEM or ABCN boards.
